"I'm not a fan of pregnancy right now with my thighs touching and my boobs changing," says JWoww, who walked the red carpet in a black gown with a plunging embellished neckline, fiance Roger Matthews by her side. "But I know it will be worth it and hopefully I get back to that really quickly."

Snooki, who is mom to Lorenzo, 1, and is expecting her second child with fiance Jionni LaValle, tells Us that her pal is just nervous about labor. "I know she is going to be a great mom. She took care of me for four years on 'Jersey Shore.'"

Meanwhile, Snooki also tells Us that she's planning her fall wedding to LaValle, but a certain "Jersey Shore" cast member won't be there: "We are not typically friends right now," Polizzi says of Mike "The Situation" Sorrentino. "If we see each other we will say hi but it’s my wedding and I will invite people who are important to me in my life. Mostly everyone else will be there though."
